Fix truncated unit test summary trace

[dougwhite]

Problem

For larger test suites, the plain text test summary can be truncated in the trace output. Here is the example output from my test runs:

TestSuite orapi_tests DONE.

SUMMARY FOR TESTSUITE orap
[Mon Jun 15 18:10:44 2026] Fetching app_exithdl from image . . . done.

The summary line should have total number of test runs / failures etc.

Cause

The full report was being concatenated into a single text= trace call, hitting the OpenROAD trace varchar limit.

Fix

Trace the separator lines separately and output the result StringObject directly.

Verification

When I export the UnitTestFramework application from OpenROAD 12.0 my xml file is completely different than the one is the repo. 🤷

So I made the change to the flat xml file on disk and then re-imported into OpenROAD and it appears to be working as expected. All tests still passing and the message is no longer truncated.

Thanks for taking the time to explain the problem AND provide a fix. Looks good!
